L. testa orbiculari, sub-globosa, tenui; bifariam sulcato-striata; striis divaricatts. 



Description. Shell orbicular, somewhat globose, thin, groove-striated in two directions, 

 strise divaricate. 



This pretty species is easily distinguished from its congeners, by its regular outline and 

 sharply cut divaricating stria?. 



It is difficult to believe a species to have so wide a distribution, both horizontally and 

 vertically, as this is said to have. It occurs in the Eocene of Europe, in the Meiocene of 

 Virginia, in South-Carolina in both Pleiocene and Post Pleiocene, and belongs to the 

 living fauna of our entire coast. 



It is very possible that several species are included under this specific name.
